Nice looking "female" - Does it have the artillery wheel trailer that would mark it out as a mk1?
Yes....... I haven't stuck it on yet otherwise I'll keep knocking it off. It will be stuck on when everything is done and the model ready for it final coat of semi-gloss lacquer.
Cheers; I'm not certain but I think you can just leave the trailer off for a mk IV female (the same trick doesn't work for males because the sponson shape changed).
